The Avengers are in the middle of training when a robot breaks into the headquarters. After disabling it, it informs them the Hulk is in the desert. The robot was sent by the Mole Man, and the Avengers are lured into his trap. They are attacked by the Minotaur, a creature belonging to the Mole Man. Quicksilver manages to get separated from the team and is captured by the Mole Man's Moloids. The three remaining Avengers trap the Minotaur and look for Quicksilver. He is freed and they defeat the Mole Man.

Notes

Captain America, Hawkeye, Scarlet Witch and Quicksilver were all last seen in Avengers #16 where the latter three joined the team to replace the original members who took a leave of absence.

While there is a Captain America story in Tales of Suspense #66, it is a flashback tale from World War II.

The events in this issue happen simultaneously with the Hulk story in Tales to Astonish #69, where the Hulk battles the Leader. All the panels dealing with the subplot involving the Hulk battling the leader originate from this issue.
